New liquid-metal membrane technology may help make hydrogen fuel cell vehicles viable

While hydrogen fuel cell cars offer advantages over electric vehicles, they have yet to take off. One reason is the high cost and complexity of producing hydrogen fuel, which can be reduced by using membranes to separate hydrogen from other byproducts. Conventional palladium membranes are expensive and fragile. A new study shows that membranes made from less-expensive liquid metals appear to be more efficient at separating hydrogen and also more durable.
